There is a sort of “pecking order” in the marketplace when it comes to live music. Generally, if you are “new” and “unproven” you will not frequently be asked to sing at churches and events with large audiences. Those places invite artists who are more popular and have some kind of following. You will likely need to focus on small churches, community organizations, and ministries. Your first performance opportunities will probably come from a relationship you have with a pastor or ministry contact.
In most cases, artists who nurture these relationships and offer their music for little or no compensation find the warmest reception and stand the best chance of being invited back.
Tips:
Research organizations and ministries in your area that are already using live music.
Begin talking with contacts with whom you already have a good relationship.
Begin building relationships with people at other organizations. Don’t beg for concerts, just become a friend.
Be content with smaller venues while you perfect your artistic craft.
Serve people with your music without expecting anything in return.
